BC-Ni307-1（NiCrFe-1）
·Ni307-1 is a Ni70Cr15 heat-resistant alloy electrode with a low-hydrogen sodium type coating. Because the weld contains Nb, the weld metal has good plasticity and crack resistance
BC-Ni327-2(NiCrFe-2)
Ni327 is a Ni70Cr15 heat-resistant alloy electrode with a low-hydrogen sodium type coating. Because there is a certain amount of molybdenum, niobium and other alloying elements in the weld, the weld metal has good crack resistance.
BC-Ni307-3(NiCrFe-3)
·Ni307-3 is a Ni70Cr15 heat-resistant alloy electrode with low-hydrogen sodium coating, because there is a certain amount of manganese and niobium alloying elements in the weld, so the weld metal has good crack resistance. Reverse DC connection is adopted.
BC-Ni307-4(NiCrFe-4)
·Ni307-4 is a Ni70Cr15 heat-resistant alloy electrode with a low-hydrogen coating. The weld metal has high strength, excellent crack resistance and high temperature oxidation resistance, and excellent low temperature impact resistance. The electrode adopts DC reverse connection
BC-NiCrMo-3
·NiCrMo-3 is a low-hydrogen sodium type coating of Inconel electrode. The weld has excellent plasticity, toughness and crack resistance. Weld metal has high strength and strong corrosion resistance at room temperature and high temperatures.
BC-NiCrMo-4
·NiCrMo-4 is a low-hydrogen sodium type coating Inconel electrode, the weld has excellent plasticity, toughness and crack resistance. Weld metal has high strength and strong corrosion resistance at room temperature and high temperatures.
